Aptamer-CRISPRCas12a-Based Lateral Flow Technique for Visualized Rapid Detection of Endogenous Damage Factor Neu5Gc in Red Meat

The N-glycolylneuraminic acid (Neu5Gc), a major salivary acid molecule found on the cell surface of animals such as pigs, cows, and sheep, can be metabolically incorporated into the body through consumption of animal-derived foods like red meat. This leads to an immune response and chronic inflammation in individuals who do not naturally produce Neu5Gc, including humans and poultry, further increasing the risk of cancer. The trans-cleavage activity of Cas12a is activated by the recognition of...
